Abstract

Water quality is vital for maternal health. In Indonesia, consuming untreated or low-quality water may increase anemia risk in pregnant women. This study examined the relationship between drinking water sources and hemoglobin levels and identified factors influencing water source selection. A cross-sectional study of 72 pregnant women was conducted at Palaran Health Center, Samarinda (Dec 2024–Jan 2025). Data on sociodemographics and drinking water sources were collected via questionnaire, while hemoglobin levels were obtained from laboratory records. Due to non-normal data distribution (p < 0.05), the Kruskal–Wallis test with post hoc comparisons was applied. Determinants of water source selection were analyzed using multinomial logistic regression. Most respondents (76.40%) consumed unboiled refilled gallon water, which was associated with significantly lower hemoglobin levels than bottled or PDAM water (p = 0.002). The logistic model was significant (χ² = 75.233, df = 54, p = 0.030; Nagelkerke R² = 0.811). Significant predictors of water source choice included number of pregnancies, abortion or fetal death history, delivery history, household income, mother’s and husband’s education levels (p < 0.05). Unboiled refilled gallon water consumption is linked to lower hemoglobin levels and higher anemia risk. Reproductive and socioeconomic factors influence water source selection. Education on safe water handling and boiling practices is essential to improve maternal hematologic health.

Abstract

This study examines the role of financial stress as a mediator in the relationship between financial self-efficacy and purchase decision making among generation Z in Indonesia. Using validated psychometric instruments and bootstrap mediation analysis, the findings reveal full mediation by financial stress with a statistically significant indirect effect. Contrary to conventional theoretical predictions, financial self-efficacy is strongly and positively associated with financial stress. In contrast, financial stress shows a significant negative predictive relationship with the quality of purchase decision-making. The direct path between financial self-efficacy and purchase decision making was not statistically significant. These empirical findings suggest that high financial self-efficacy may paradoxically increase psychological burden and performance expectations in Indonesia’s digital era, thereby intensifying stress levels that undermine cognitive decision-making. This study contributes novel insights into counterintuitive psychological mechanisms that underlie financial behavior in the context of Indonesia’s digital transformation, highlighting the importance of integrating stress management into financial education programs targeting generation Z.

Abstract

This study examines the effect of bank income diversification on the market value of Indonesian banking firms. The sample consists of eight banks listed on the Indonesia Stock Exchange over the 2015 to 2021 period. Income diversification is measured by the proportion of Net Non-Interest Income (NNII), market value is proxied by Tobin’s Q, and bank profitability, measured by return on assets (ROA), is included as a control variable. The sample was selected purposively based on data availability and consistency, resulting in 56 observations. The study employs multiple linear regression analysis. The results indicate that income diversification has a positive and statistically significant effect on market value. These findings suggest that diversifying income sources can enhance bank valuation and encourage banks to expand non-interest income streams to sustain value creation. However, the study is limited by its sample size and observation period, which leaves room for broader future research. Theoretically, the findings support signaling theory and portfolio theory, which suggest that income diversification can serve as a positive signal to investors while reducing the risks associated with dependence on interest income. In practice, the study highlights the importance of income diversification strategies for improving market valuation and strengthening the competitiveness of Indonesian banks.

Abstract

Dalam konteks pedagogi abad ke-21, pemanfaatan teknologi informasi melalui media seperti video interaktif sangat penting dalam meningkatkan kualitas pembelajaran. Studi ini dilakukan untuk mengetahui tingkat validitas, kepraktisan, dan efektivitas video pembelajaran berbasis pendekatan Pengajaran dan Pembelajaran Kontekstual (CTL), yang dikembangkan menggunakan Macromedia Flash 8 untuk meningkatkan kemampuan penalaran matematika siswa. Desain Penelitian dan Pengembangan (R&D), mengikuti kerangka ADDIE (Analisis, Desain, Pengembangan, Implementasi, dan Evaluasi), digunakan dalam penelitian ini. Instrumen pengumpulan data meliputi lembar validasi, lembar observasi implementasi pembelajaran dan aktivitas siswa, kuesioner respons untuk guru dan siswa, dan tes kemampuan penalaran matematika. Partisipan adalah siswa kelas VIII.1 SMPN 2 Watansoppeng. Hasil penelitian menunjukkan bahwa media pembelajaran mencapai kategori 'sangat valid' dengan skor validator 3,79. Dari segi kepraktisan, media tersebut mendapat tingkat respons 'sangat positif' sebesar 88,46%, dan implementasi pembelajaran 'terlaksana sepenuhnya' dengan skor 1,87. Efektivitasnya ditunjukkan oleh tingkat respons siswa yang positif sebesar 82,36%, tingkat aktivitas siswa yang 'baik' sebesar 71,66%, dan skor kategori 'baik' sebesar 79% pada tes kemampuan penalaran matematika. Oleh karena itu, disimpulkan bahwa video Pembelajaran dan Pengajaran Kontekstual yang dikembangkan untuk siswa kelas delapan di SMP Negeri 2 Watansoppeng merupakan alat pembelajaran yang valid, praktis, dan efektif. Pemanfaatan informasi teknologi, khususnya penyajian pengetahuan melalui video interaktif, dapat meningkatkan pembelajaran bersama di abad ke-21. Penelitian ini bertujuan mengetahui tingkat kevalidan, kepraktisan, dan keefektifan pengembangan video pembelajaran berbasis pendekatan Contextual Teaching and Learning (CTL) berbantuan macromedia flash 8 untuk meningkatkan kemampuan penalaran matematis peserta didik. Jenis penelitian ini adalah penelitian Penelitian dan Pengembangan dengan pengembangan model ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Instrumen yang digunakan adalah lembar validasi, lembar observasi keterlaksanaan pembelajaran, lembar observasi aktivitas peserta didik, angket respon guru, angket respon peserta didik serta tes kemampuan penalaran matematis. Subjek penelitian adalah peserta didik kelas VIII.1 SMPN 2 Watansoppeng. Hasil penelitian menunjukkan pencapaian analisis validasi oleh tim validator adalah 3,79 dengan kategori sangat valid. Kriteria kepraktisan 88,46 % dengan respon sangat positif dan observasi keterlaksanaan pembelajaran 1,87 dengan kategori terlaksana seluruhnya. Hasil kriteria keefektifan 82,36% dengan respon positif, hasil analisis observasi aktivitas peserta didik 71,66% dengan kategori baik, dan kemampuan penalaran matematis peserta didik 79% berada pada kategori baik. dapat disimpulkan video pembelajaran berbasis pendekatan Contextual Teaching and Learning berbantuan Macromedia Flash 8 pada peserta didik kelas VIII di SMP Negeri 2 Watansoppeng yang telah dikembangkan dinyatakan valid, praktis, dan efektif.
